This project is the next phase of the Main Canal Rehabilitation Project. The project includes the abandonment of Pumping Plants 4 and 5 and the construction of a new Pumping Plant 4 and Pipeline to the old discharge of Pumping Plant 5. Features about this pump station include: 1) the ability to convey up to 200 cubic feet per second (cfs) through the pump station towards the 5th lift, 2) automating the heads of laterals 4-north and 4-south, 3) the ability to drop water from the 4th and 5th lifts back into the 2nd and 3rd lifts of the Main Canal, and 4) modernizing and automating the operation of the Main Canal.

This project was originally developed to address canal issues with 2N because of the canal constantly failing, it was intended to rebuild the canal to its original design. In the design process it was determined that in conjunction with the operations of the northside reservoir and the interconnections along Fruit Avenue, moss and algae bloomed so bad that water would be blocked from moving down the canal. Therefore, it was determined that piping the lateral would provide two major benefits: 1) prevent bottlenecks caused from moss and algae growing in the sunlight, and 2) address the failing canal.
In addition, after the bids were opened and due to the pricing of the project being below what the District has seen before, staff had the contractor bid to pipe M lateral between Poppy and Sperry Avenues. M Lateral in this location had massive access issues, and problems with vagrants dumping their trash into the canal. Piping the lateral provided security, safe maintenance and ease of operation.

This project was the number one priority item listed on the capital improvement plan. The project would relocate the pump station that was on lateral 3-south at Marshall Road and relocate the pump station to the south side reservoir. The goal was set to optimize the usage of the two drains project and to not impact the operations of 3-south.
